PROBLEM TO BE SOLVED: To provide a configuration that safely performs a check of a working unit, by stopping only the working unit of an agricultural work machine.SOLUTION: An agricultural work machine includes working units A1, A2 where the driving force of a drive unit B1 is transmitted as power and operates. The agricultural work machine includes: switching units C10, C20 arranged in the agricultural work machine A and connected to go over to the drive unit B1 and the working units A1, A2, and operating to switch the power of the drive unit B1 into a power transmission state and a power cutting state to the working units A1, A2； and an agricultural work machine side communication unit C30 included in the switching units C10, C20, and transmitting and receiving a control signal. The switching units C10, C20 are controlled so as to perform switching operation based on the control signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】農作業機の作業部のみを停止させて、作業部の点検を安全に行う構成を提供する。【解決手段】駆動部Ｂ１の駆動力が動力として伝達されて動作する作業部Ａ１、Ａ２を備えた農作業機であって、農作業機Ａに配置されていると共に、駆動部Ｂ１と作業部Ａ１、Ａ２とにわたるように接続され、駆動部Ｂ１の動力を作業部Ａ１、Ａ２に対して動力伝達状態と動力切断状態とに切り換えるように動作する切換部Ｃ１０、Ｃ２０と、切換部Ｃ１０、Ｃ２０に備えられ、制御信号を送受信する農作業機側通信部Ｃ３０とを備え、切換部Ｃ１０、Ｃ２０は、制御信号に基づいて切り換え動作するように制御されている。【選択図】図１
